I have an 11 year old accentra pellet stove that stopped working last night. I took everything apart and cleaned it and went to refire. Nothing. In the test mode the distribution fan works and I can hear and "feel" the combustion motor TRYING to work. Feed motor wasn't. I helped the combustion motor by spinning the fan and it started up for about 20 seconds on its own but then died. Any advice? Its very cold out and my only source of heat while remodeling continues.
